双辊式带钢铸轧过程工艺稳定性研究

Study on Technologic Stability of Twin Roll Casting Strip Process

采用有限差分法对双辊式带钢铸轧过程进行了三维数值模拟,分析了铸轧速度和浇铸温度对铸坯凝固过程的影响,得出了铸轧速度、铸轧辊径和带厚之间的关系以及适宜的浇铸温度,从而为带钢的稳定生产和控制带钢铸轧过程打下理论基础。

The solidincation of twin roll casting strip process is simulated by three-dimensional finite difierence method. The influence of roll-casting speed and casting temperature on solidification is also analyzed.The simulated results give not only the relation of roll-casting speed,roll radius and strip thickness, but also the proper casting temperature, which can promde the theoretical bases to the stable production of strip and the control on strip roll-casting process.
